Is there an IIS 7.5 Web Site View that looks anything like the IIS 6 Web Site Properties view? I know where everything is in IIS6 (host headers, redirections, default filename etc.), but the view in IIS 7.5 is completely different. Is there anyway to access a traditional view in IIS 7.5?
If not, how would I access these features in IIS 7?
Not that I'm aware of. But if you play with it, I think you'll grow to like it (I did).
Host headers: Select Web site > under IIS > HTTP Response Headers or under Actions on the right-side > Bindings ...
Redirections: I've always just installed URL Rewrite (via Web Platform Installer) and have used that. Otherwise IIS 7.x writes to Web.config, so you could go that route. More about HTTP Redirects - via the interface it requires a feature be turned on, as detailed in the article.
Default filename: Select Web site > under IIS > Default Document
This won't fit as a comment, so to answer your question about redirecting all requests to another domain:
.*
Note that if you want to use a canonical domain (so force www.domain.com or domain.com, or even altdomain1.com to go to domain.com) there's some nice templates already created under the SEO heading - Canonical domain name in particular (which I've found very valuable).
EDIT: I suppose you could also add google.com as a domain to the site, and then use the method detailed in http://weblogs.asp.net/owscott/archive/2009/11/30/iis-url-rewrite-redirect-multiple-domain-names-to-one.aspx since it's unlikely google.com would point to your server. However, that smells like a hack to me, so I don't know that I'd recommend it.
